# Change Log
## [Unreleased] - ReleaseDate

### Added
- Add `mips32r6` and `mips64r6` support for signal, ioctl and ptrace
([#2138](https://github.com/nix-rust/nix/pull/2138))

### Fixed
- Fix `SigSet` incorrect implementation of `Eq`, `PartialEq` and `Hash`
([#1946](https://github.com/nix-rust/nix/pull/1946))

### Changed

- The following APIs now take an implementation of `AsFd` rather than a
`RawFd`:

- `unistd::tcgetpgrp`
- `unistd::tcsetpgrp`
- `unistd::fpathconf`
- `unistd::ttyname`
- `unistd::getpeereid`

([#2137](https://github.com/nix-rust/nix/pull/2137))
